CPC1560 Block Diagram 1 NC CPC1560 60V, 300mA, High Speed Normally Open Relay with Integrated Current Limit Description The CPC1560 is a Single Pole, Normally Open (1-Form A) optically isolated MOSFET switch that provides fast turn-on of loads up to 600mADC in the DC-Only configuration or 300mArms in the AC/DC configuration; active current-limiting circuitry; and 3750Vrms of input to output isolation. Turn-on is minimized with the use of an optional external storage capacitor that provides the necessary charge required by the internal switching MOSFETs. The device charges this capacitor through bootstrap diodes from the load voltage thereby alleviating the need for an additional power supply. A fast, but slightly slower turn-on is available without the external charge stora...
